The correct option is C its bond energy is high
Antimarkownikoff's addition takes place in the presence of H2O2 and the formation of free radicals take place. But in case of HCl, the H−Cl bond has very high energy and large amount of energy is required for the formation of H and Cl free radicals, hence the reaction is endothermic. Such large amount of energy is not available and formation of free radicals does not take place.
